To all whom t may concer-a: Be it known that I, PATRICK WALL, a eltizen of the United States, `residing in Pitts# bur h, in the county of Allegheny and State of ennsylvania,have invented a new and useful Improvement 1n Cans or Receptacles,

of which the following is a full, clear, andF exact description.

The present invention relates broadly to cans or receptacles, and more particularly i to devices of this nature .adapted to be used as ice molds in the iicia-liice.

An .important object of\the' present inmanufacture of artivention is to provide a mo1d particularly adapted for use in the manufacture of ice from natural or raw Water as distinguished from distilled water.

Another obect of the invention is to provide a mold wlth a pressure or agitating pipe formed integral therewith during the manufacture of the mold.

Still another object ofI the invention is to erence to the accompanying specification and drawings forming apart thereof, it being premised that changes may be made in the various details and manner of o erationy claimsJ within the scope `of the appende without departing from the spirit of lthe invention. v Figure 1 is a top plan view of a mold constructed in accordance with the present Figure 2 is a vertical sectional View through a portion of the mold taken on' the It is well known tolthose familiar with `the artof refrigeration that in making ice fromnaturaho raw water,d it is essential to maintain the `water in a state of agitation duringthe freezingto gradually move V:sis

l the-impure water andthe,sediment toward the upper portion of th3""mold.\Y `In this VHeretoiore various methods of agitation i have been employed, but one of the slmplest has been to pass air under pressure throu h a pi e soldered to one of the walls of t e mol Due to the fact that the molds are usuall constructed of galvanized material,

it is ificult to 'effect a firm union between' the molds and the pi es, and the pipes have had a tendency -to lreak awa from the molds with the cake of ice. ith a mold constructed in accordance with the present invention, the` foregoing disadvantages are entirely eliminated. y

Referring more particularly to the drawings, there is illustrated a rectangular mold of gradually tapering formation'having the `usual endwalls 2 and side walls 3. A; bot-` tomf4 may be secured lin position in any desired manner as is customary in this art and, if desired, reinforcing means 5 ma be rovided for certain portions'lof'the mol ccording to the presentinvention, one of lthe end walls 2, during the manufacture of'the. mold, has a portion 6 adjacent one edge thereof bent inwardly towardv the interior of the mold and then bent upon itself as indicated at 7, to form an air lpipe 8l extending the entire depth of the mol The edge portion 9 of one of the side walls 3 is then bent over the edge 7 andthe parts have rivets 10 passed` therethrough to-secure the same firmly in position. It is desirable, after the riveting operation has taken place, to scour the edges 11 and a portion 12 of the end wall 2, and then immerse the corner of the mold in a molten bath of solder which flows into the crevices and forms a tight joint at the corner of the mold.

Suitably-secured in the upper end of the pipe 8 is anangular nipple 13 adapted to have a pressure hose 14 connected thereto 4for blowing air into the pipe. At its lower end the preferab ing 16 formed in the sidewall of the pipe 8 to permit the air to pass into the body 0f water and thoroughly agitate the same. The plug 15 may be 'of any suitable length so` that the opening 16 for the admission of air may be at any desired point. During the soldering operation, as before described, a small amount of air may be passed through the pipe 8 may be closed by a plug 15, y sweated'in position, and having. its upper end terminating adj acntan openpipe Sto prevent thesolder,

so l,

u from -ownglnto the interiorthereof. By r manner a clear cake of ice can be prducedmreasogn of the present ontructlomit will be apparent that there is provided an airpipe which is an integral part of the mold structure, and there is no tendency for the pipe to become loosened or displaced during the freezing operation, or the subsequent removal of the cakes of ice from the mold.

The advantages of the present invention arise from the integral construction provided whereby the handling'ofrthe molds is facilitatedl and the durability greatly increased. I

l claim:

1. As an article of manufacture, an ice mould having a portion of one of the Walls bent over upon itself to form an air pipe, means for simultaneously securing said bentover portion and an adjacent wall of the tank together, and means for closing one end of the pipe, substantially as described.

2. As an article of manufacture, an ice mold having an edge portion of one of the 4walls overlapped upon itself to form an air pipe, means for securing said overlapped portion to the adjacent wall of the tank to provide a seamless closure' between the interior of the pipe and the interior of the tank, and means for closing one endof the pipe, substantially as described.

3. receptacle, having a` complete pipe formed as an integral part thereof and extending substantially parallel With one wall of the receptacle, there being a seamless portion of )the receptacle body constituting the portion of the wall of said pipe lying in the interior of the receptacle, substantially as described.

4. A receptacle, having a complete ipe formed as an integral part thereof andextending substantially parallel with one wall of the receptacle throughout substantiallyl one dimension thereof, there beinga seamless integral portion of the rceptacle body constituting the portion of the' wall of said stantially as described.

A receptacle, having one of the walls thereof shaped to form a complete air pipe with a portion of the wall forming a seampipe lyingin the interior of the receptacle, su

less closure between the interior of the pipe and the interior of the receptacle, substantially as described.

6. A substantially rectangular receptacle, having a complete air pipe formed asan integral part Ithereof and located adjacent one of the corners of the receptacle with a portion of the receptacle body forming a seamless closure between the interior of the pipe and the interior of the receptacle, substantiallyas described. v

7 -As an article of manufacture, a metallic ice mold having one of the walls thereof bent upon itself to form a complete integral air pipe having a seamless inte ral metallic wall intermediate the interior o the pipe and the interior of the mold,- substantlally as described.

mold having one of the walls bent over upon itself to lform a complete integral air pipe presenting a seamless wall to the interior of thex'nold, and means fdr securing said bent over portion to the adjacent wall, substantially as described. i

10. As an article of manufacture, an ice mold having one of the walls bent over upon itself adjacent one corner of the mold to form a complete integral air pipe presentin a seamless wall to the interior of the-mold?, and means for securing said bentover portionto the adjacent wall, substantially as described.- g

In testimony whereof, I have hereunto set my hand. A
